Abstract

A spring assembly for a vehicle chassis may include a spring that features a coating, a spring support, and an intermediate layer. The intermediate layer can be arranged between the spring and the spring support. The intermediate layer may be at least materially connected to the spring, in particular to the coating on a side facing the spring. The intermediate layer lies entirely or partially against the spring support on a side facing away from the spring and is connected to the spring support by a connection other than a material connection.
